4. 7. 6. Checking and cleaning of fuser roller and pressure roller

(1) Handling precautions
• Do not leave oil (fingerprints, etc.) on the fuser roller.
• Be extremely careful not to allow a hard object to hit or rub against the rollers because the thin
teflon layer coated on the aluminum substrate is easily damaged and, if damaged, will result in
defective drum cleaning.
(2) Checking
• Check for stain and damage to the fuser and pressure rollers and clean or replace if necessary.
• Clean the upper/lower separation fingers and check for chipped claws.
• Check the cleaning condition of the cleaning WEB and cleaning roller (kinks, lines and slacks
on the cleaning WEB).
• Check the thermistor for proper contact with the fuser roller.
• Check the fused condition of the toner image.
• Check the gap between the lower entrance guide and pressure roller (do not make them touch
each other).
• Check the gap between the fuser roller and thermostat (2~2.5mm).
• Check the fuser and pressure rollers for proper rotation.
• Check the fuser and pressure rollers for bearing.
• Check the fuser roller drive gear and cleaning WEB drive gear
• Check the WEB motor lubrication to the warm gear (white molycote).
(3) Cleaning procedure for fuser roller
When the fuser roller becomes dirty, it will cause paper jamming. If this happens, wipe the roller surface
clean with cotton moistened in alcohol. For a better cleaning effect, clean the roller when it is still warm.
Note: Be careful not to rub the teflon-coated surface with your fingernails or hard objects because it is easily
damaged. Do not apply the silicon oil to the fuser roller.
